RAILWAY SWITCH.

Application filed December This invention relates to railway switchesand has for an important object thereof the provision of a froglesscontinuous rail switch.

A further object of'the invention is to provide in a device of thischaracter a coning elements are only supported at the crossover point.

A further and more specific object of the invention isthe provision in adevice of this character of a construction, wherein tapered rails areemployed to raise the level of the switch to such a point that where acrossover occurs, a relatively heavy switch rail section may be used, sothat an adequate support will be provided at the cross-over point duringthe switching operation.

These and other objects I attain by the construction shown in theaccompanying :5 drawings, wherein for the purpose of illustration isshown a preferred embodiment of my invention and wherein Figure 1 is aplan view showing switch mechanism constructed in accordance with myinvention the switch points being indicated in solid lines ininoperative position and in dotted lines in switchng position;

Figure 2 is a section on the line 22 of Figure 1;

Figure 3 is a section onthe line 33 of Figure 1;

Figure 4 is a section on the line t4 of Figure 1; p 1

Figure 5 is a section on the line 55 of Figure 1.

Referring now more particularly to the drawings, the numerals 10and 11indicate the'rails of a right-of-way, which may be of any usual orpreferred construction. In accordance with my invention,'1 associatewith the rails 10 and 11 pivoted switch points 13 and 14, of which theswitch point 18 is constructed to overlie the rail 10 and the switchpoint 14 to abut against the rail'll. Each of the switch points 13 and14 is of considerable length and is tapered throughout-"its length. Inthe case of the switch point 13, the portion thereof whichoverlies therail 10 when in switching position is wedge-shaped increasing inthicknes from a 28, 1927. Serial No 243,191.

thin tip portion to a point where it is of a thickness greaterthan thedepth of the flange of the rail. From this point on, the switch point 18begins to diverge from the rail to the point of its pivotal connectionto the switch track rail 15. The switch point 14v may be somewhatshorter than the switch point 13 and, except for its taper, constructedafter the manner of constructing ordinary inside switch points. Theswitch point 14 is pivoted at its end tothe inside switch track section16.

At the cross-over connection between the inside switch track 16 and therail 10, I employ a base 17 having castings 18 and 19 mounted thereon,this base extending be- 'neath the cross-over connection andto theoutside switch rail 15, where it supports a guard rail 20. The casting18 has at its forward end a slot 21 receiving and fitting the web andbase of the inner end of the switch track section 16, and has its uppersurface 22 arranged in the same plane as the under surface of the head23 of the switch rail section 16 and the upper surface of the head ofthe main track rail 10.

At the included angle between the casting 18 and rail 10, the casting isprovided with a projection 24; forming a filler block engaging" the rail10. Upon its upper surface adjacent its outer face, the casting 18' isprovided with an upstanding rib 25, the

inner face of which forms a continuation surface of this casting at 26is a cross-over switch point 27 adapted to swing from" a position whereit substantiallyparallels the head of the rail 10 and lies outwardlythereof to a position where it extends across the head of the rail 10,has its free end in engagementwith the inner face of the rib 25 of thecasting 18 and bridges the gap between the heads of the 'railsections 16and 16" of therinner switch rail. I
